Sensor disk free

What kind of device is the F drive on this machine?

It's external hard disk, WD Passport

The error message is indicating that whatever that host machine is sending us is erroneous data. I would imagine because it's a portable hard drive.

If you want to turn on Write Sensor Result to Disk in the Settings tab under Result Handling, we can see what it's sending us.

Masmi,

I'm going to ask my developers about this.

Masmi,

Can I ask you to try using our WMI Tester for this machine?

https://www.paessler.com/tools/wmitester

There is an option in the tester for disks. Please run it, and send the results.

Thanks!

Please check file system permission on volume root folder for wmi user.

This was reason for this error in my case.

Kind regards, Chris
